- The Visual Object Tracking challenge VOT2019 is the seventh annual tracker benchmarking activity organized by the VOT initiative. Results of 81 trackers are presented; many are state-of-the-art trackers published at major computer vision conferences or in journals in the recent years. The evaluation included the standard VOT and other popular methodologies for short-term tracking analysis as well as the standard VOT methodology for long-term tracking analysis. The VOT2019 challenge was composed of five challenges focusing on different tracking domains: (i) VOT-ST2019 challenge focused on short-term tracking in RGB, (ii) VOT-RT2019 challenge focused on "real-time" short-term tracking in RGB, (iii) VOT-LT2019 focused on long-term tracking namely coping with target disappearance and reappearance. Two new challenges have been introduced: (iv) VOT-RGBT2019 challenge focused on short-term tracking in RGB and thermal imagery and (v) VOT-RGBD2019 challenge focused on long-term tracking in RGB and depth imagery. The VOT-ST2019, VOT-RT2019 and VOT-LT2019 datasets were refreshed while new datasets were introduced for VOT-RGBT2019 and VOT-RGBD2019. The VOT toolkit has been updated to support both standard short-term, long-term tracking and tracking with multi-channel imagery. Performance of the tested trackers typically by far exceeds standard baselines. The source code for most of the trackers is publicly available from the VOT page. The dataset, the evaluation kit and the results are publicly available at the challenge website(1).

- Molecular ruthenium catalysts were found to selectively catalyze the oxidation of thioanisole to sulfoxide with a yield up to 100% in the presence of visible light and sacrificial reagents when they were anchored onto hematite powder. The composite photocatalysts also showed about 5 times higher efficiencies in benzyl alcohol oxidation than the system composed of dispersed molecular catalysts and hematite particles in aqueous solution. A photoelectrochemical cell based on a molecular catalyst modified hematite photoanode was further fabricated, which exhibited high activity towards the oxidation of organic substrates.

Konferensbidrag (refereegranskat)abstract
- The Visual Object Tracking challenge VOT2018 is the sixth annual tracker benchmarking activity organized by the VOT initiative. Results of over eighty trackers are presented; many are state-of-the-art trackers published at major computer vision conferences or in journals in the recent years. The evaluation included the standard VOT and other popular methodologies for short-term tracking analysis and a “real-time” experiment simulating a situation where a tracker processes images as if provided by a continuously running sensor. A long-term tracking subchallenge has been introduced to the set of standard VOT sub-challenges. The new subchallenge focuses on long-term tracking properties, namely coping with target disappearance and reappearance. A new dataset has been compiled and a performance evaluation methodology that focuses on long-term tracking capabilities has been adopted. The VOT toolkit has been updated to support both standard short-term and the new long-term tracking subchallenges. Performance of the tested trackers typically by far exceeds standard baselines. The source code for most of the trackers is publicly available from the VOT page. The dataset, the evaluation kit and the results are publicly available at the challenge website (http://votchallenge.net).

An iron-based thin film as a highly efficient catalyst for electrochemical water oxidation in a carbonate electrolyte
- 2016

- A highly active iron-based water-oxidation catalyst was electro-deposited from a CO2 saturated bicarbonate solution containing Fe2+. This catalyst (Fe-Ci) produces a current density of 10 mA cm(-2) at an overpotential of 560 mV and the activity remains constant over 18 h in the environmentally benign HCO3-/CO32- buffer (pH 9.75). A Tafel slope of 34 mV dec(-1) was obtained for Fe-Ci, which is lower than other reported values for iron-based catalysts.

Photocatalytic water oxidation via combination of BiVO4-RGO and molecular cobalt catalysts

Tidskriftsartikel (refereegranskat)abstract
- A BiVO4-reduced graphene oxide (RGO) composite in conjugation with the cubic molecular complex Co4O4(O2CMe)(4)(py)(4) (py = pyridine) has been found to be highly efficient towards visible light-driven water oxidation. A 4-fold enhancement in the average oxygen evolution rate and 100% yield based on the consumption of the sacrificial electron acceptor were obtained upon the addition of molecular cocatalysts to BiVO4-RGO in pure water.

- Water and energy are intricately connected in households. The connections mainly appear in three types of residential behavior: bathing, cooking, and cleaning. This study investigated the features of water and related energy consumption in groups with different individual attributes and identified the key groups and types of behavior that correlate with water and energy conservation. A face-to-face interview method was applied to estimate residential water and energy consumption associated with three types of behavior. Regression analysis was applied to the results of 1017 questionnaires to explore the relationships between individual attributes and the amount of water used and associated energy consumption. Chi-square test and extended Mantel-Haenszel test were applied to confirm the relations between individual attributes and behavior. Annual per capita water use for the three types of behavior was 33.6 m3 on average and annual per capita water related electricity consumption was estimated to be 545.7 kWh. The Pearson correlation coefficient was 0.8 with a confidence level of 99%, which indicated a strong correlation between water use and energy consumption. The results showed that 55% of household electricity consumption was coupled with water use in Beijing. Water use and related electricity consumption had a positive correlation with education but a negative correlation with age and family size. Young women under 30 years old with a bachelor degree or above who live alone often use the most water and electricity, 16% and 28% higher than the average. This paper provides a better understanding of urban household consumption and individual attributes.

- We studied dampness and mold in China in relation to rhinitis, ocular, throat and dermal symptoms, headache and fatigue. A questionnaire study was performed in six cities including 36 541 randomized parents of young children. Seven self-reported signs of dampness were evaluated. Multilevel logistic regression models were used to calculate odds ratios (ORs). Totally, 3.1% had weekly rhinitis, 2.8% eye, 4.1% throat and 4.8% skin symptoms, 3.0% headache and 13.9% fatigue. Overall, 6.3% of the homes had mold, 11.1% damp stains, 35.3% damp bed clothing, 12.8% water damage, 45.4% window pane condensation, 11.1% mold odor, and 37.5% humid air. All dampness signs were associated with symptoms (ORs from 1.2 to 4.6; P < 0.001), including rhinitis (ORs from 1.4 to 3.2; P < 0.001), and ORs increased by number of dampness signs. The strongest associations were for mold odor (ORs from 2.3 to 4.6) and humid air (ORs from 2.8 to 4.8). Associations were stronger among men and stronger in Beijing as compared to south China. In conclusion, dampness and mold are common in Chinese homes and associated with rhinitis and ocular, throat and dermal symptoms, headache and fatigue. Men can be more sensitive to dampness and health effects of dampness can be stronger in northern China.
